VoLTE, in simple terms, refers to Voice over LTE aka 4G cellular network – meaning voice calls are served over a 4G LTE network rather than fallback to 2G or 3G connections. With VoLTE, you can have simultaneous usage of voice and cellular data – so no more tethered data connection drop while using the phone call.
So, why now VoLTE with Nepal Telcom?
This might be a good question when the world was using 4G and VoLTE many years ago, we are finally at least able to use at some places. Thanks to Nepal Telecom’s effort and NTA’s approval of the same.
To be able to make a VoLTE call, the device, its firmware, and the mobile telephone provider must all support the service in the area and be able to work together. This has just been possible with Nepal Telecom’s VoLTE capable 4G networks. Go to Settings and then to ‘SIM cards & mobile networks’. Check if there is any option as “VoLTE” or “Enhanced 4G”. If yes, then your phone supports VoLTE.
How to activate NTC VoLTE?
Nepal Telecom (NT) has started test trial of VoLTE service on the occasion of World Telecommunication & Information Society Day ie May 17th, 2021. On this trial phase, NT is offering free 100 minutes of VoLTE voice call valid for 28 days for its VoLTE activated users.
- Ensure you have a 4G capable phone (800 band 4G support)
- Ensure your NT SIM card is 4G activated
- Dial *444# to activate VoLTE in NT SIM card
- Enable VoLTE setting in your smartphone from Mobile network settings, if there is no VoLTE setting in your phone then this feature is enabled to adapt to NT network automatically. No user action is required.
- Once activated, dial *111# to get the free VoLTE voice calls for 100 minutes for free.
Once activated, whenever you are in NT 4G network you are using VoLTE as long as your smartphone supports this technology. Nepal Telecom has published a list of tested smartphones from Samsung, Xiaomi and Nokia that supports NT VoLTE 4G feature.
VoLTE has been marked as HD Voice quality by Nepal Telecom but we are yet to see if there is really high-def voice fidality in the NT’s 4G VoLTE network services. We hope VoLTE-HD voice services from NT gets improved in near future.
In some phones, you might see 4G network calling feature which is equivalent to 4G VoLTE voice calling.
